Hi All,
I have a 2014 Mk7 Golf R and the previous owner advised he had coded the exhaust flaps with his OBDeleven to be open all the time.
Regardless of drive mode, rpm, sport, normal, eco etc.. they stay open.
I check and set long coding byte 9, bit 2. I have tried unticking, drive the car, then tick again - no change. Tick means flaps installed. Unticked means not installed.
The flaps themselves are working fine via ECU - I used the OBDELEVEN output test for the left and right exhaust flaps and they both cycle (open/close/open/close etc.. fine.)
I have logged the data and they show OPEN and 90% all the time no matter what I try.
The car is stage 2 with EQT. I checked with them and the exhaust flaps table/settings are all OEM so should not be an issue.
I have tried disconnecting the battery for an hour - no change. It looks like the ECU can control the flaps, its just always telling them to be open.
Any idea how to get this working? Is there a special process for reverting back to automated open/close control ?
